how can a light particle travel at the speed of light without being infinitely heavy? Any mass accelarated to the speed of light becomes infinitely heavy.

What am I missing?

There is a connection between the Micro and the Macro levels. One is constrained by the constancy of the speed of light when thought engines are created to answer special theory. Why is it that one can only work with the constancy of light and why is there so much confusion about this.?

water flows (v=0) over a dam at the rate of 650kg/s and falls vertically 81 m before striking the turbine blades.
Calculate (A) the speed of the water just before striking the turbine blades (ignore air resistance)
and (B) the rate at which mechanical energy is transferred to the turbine blades, assuming 58% efficiency.

I had a really cold bottle of water in the fridge, but there was no ice in it at all, none of it was actually frozen. When I poured it into my cup it turned to ice slush before my eyes. I repeated this stunt and my sister witnessed it, but I cannot explain it. It seemed to work better if I poured the water very quickly.

a block of mass sliding without friction along a single looped track is to remain on the track at all times, even at the very top of the loop radius.
A) in terms of the given quantities, determine the minimum release height. Next if the actual release hight is 2h, calculate (B) the normal force exerted by the track at the bottom of the loop, (C) the normal force exerted by the track at the loop's top and (D) the normal force exerted by the track after the block exits the loop onto the flat section. note: the mass is under the top of the loop.

The electrocution was done using an insect electrocuter, shaped like a tennis racket. The rotation was instantanous, which means it started immedately after the racket was lifted. There was no physical force exerted at the sides that could cause a torque. Even if there was, the friction would not have allowed the insect to rotate for long. Air was stationary also. Could it be due to unequal distribution of charges that caused centripetal motion, or could there be some other reason? What do you think? I'm puzzled...

A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to six times her weight as she goes through the dip. If r = 20.5 m, how fast is the roller coaster traveling at the bottom of the dip in m/s?

suppose a roller coaseter passes point one (summit of a hill) at a height of 35m amd a speed pf 1.70m/s. if the average force of frictions is equal to one-fifth of its weight, what speed will it reach point 2 (the bottom of the hill) at 0m? the distance traveled is 45.0m.

It cant be because of increased surface area or anything of that sort, because friction is independent of area of contact
